Be it' knovvn that I, ALBERT HENRY Jacne"v soN,'a subject of the King of Great Britain,

residing at Lamorna, Woodlands "Villas; Musvv'ell. Hill Road, London, England, have invented new and'usefulImprovements in Advertising Devices, of which the following is a specification.

'Th'is invention relates to moving advertisi'ngv devices for use upon orlin connection Y with electrically propelled vehicles, and has for its object'the provision ofmeans Where-J by such devices may be intermittently 3'0 tuated in accordance with interruptions or variations of the current fioWingin the circuit of the propelling motor or motors of the vehicle. It is an essential feature of the invention that the advertisements can be changed at irregular intervals which may depend .upon'the exigencies ottraific, in contradistinction to their being changed at regular, fixed, or predetermined intervals or places as is usually the case. In the present invention the device is'so'constructed that there occurs an actuation or 'the mechanism for changing the advertisethat' type of advertising device in which a v tisements rollers;

flexiblescreen carrying a series-of a dver passes over. a ,rotating roller on In carrying out the invention I mayconveniently employ an I electro-magnet or solenoid the energizing coil of which is connected in the circuit of the propelling motors the moving armature'or core oftheelectio magnet 01'- solenoid being. connected ,to'suit able mechanism adapted to transmitmotion to the advertisingdevice. Said mechanism may be of any convenient type but '"l p'refe f to employ a ratchet and pawl mechanism having a propellingfpawl connected to the core of a solenoid, the pavvl serving todrive a toothed Wheel connected to. the moving advertisement. A I

"The core of thesolenoichwhen the solenoid 922. j Serial no; 556,118.

is de energiZedQis returned to its original gravity or through the position either ,by action of ,a'spring. I hen current flows in portion of a" revolution to to its original position carrying Withfit the g the circuit of the propelling motors the solenoid is energized and its core moves the propelling pawl which "imparts a v i the: toothed Wheel. lVh'enthe current in themo'toncircuit is interrupted or sufficiently reduced the core of thesolenoid moves back pawl in readiness for further actuation of the ltoothed Wheel; It Willithu's "be seen l that successive operations of supplying and reducmg or cutting oil current tothe' motors of the' vehicle result in the intermittentrotm" tion of the toothed Wheel and consequent I progressive actuatio n' ofthe advertising de It will further be apparentthat complete interruption of themotor circuit lintervals' is not essential to the operation of the "device butthat by suitable]arrangement oi, the solenoid or electro-magnet the "device may be actuated by variations in stren th of the current flowing in the motor circuit.

In the accompanying drawings which illustrate the inventionas applied""to an electrically drive'ntram car Figure 'l is a front elevation partly in section Figure, 2'

is anend view partly in section, and Figures',3, 4 and5are diagrams showing the 1 is ayframe havlng n its front-an openmg 2; 'Rotatably' mounted in bearings'on.

ethe endsl'of the frame 1 is ajishaft 3';-

Wiring connections;

with hichis a jhexag'onal prism orfidrum 4 each side of which "comprises a frame- Work containing'a sheetfofglass5 on which ani'advertisement or transparency can be mounted. "6 is aI guide,. the[ lovverv end of which is screwed into a socket 71fixedto the bottom of "the 'framewhilst the upper end a '100 the guide 6 is flanged to form a bracket j 8 which is fiXed to one endjofthe frame3 1',

Slidably mounted on the guide 6 is across headl9 to which a stirrup '10 is connected at its lower end bya pin 11. Theupper end of the stirrup lOisfiXed' to i ihr z core l2.

the frame 1;- Pivotally mountedfjon the pin 11 is a 'pawl 1% adapted to engage 'a ratchet 15 "fast on the shaft 3. [The ratchet wheel hasv as many teeth as there aresides to 'the drum 4, in thisinstan'ce six. '16 is aspring 1 l catch mounted on the guide 6 and adapted to engageany one of the teeth of the ratchet p the car rheostat.

19, as shown in Figures 3, 4L and 5, in which 20 shows an overhead wire supplied with current, 21 a trolley pole leading current to a terminal 22 connected by a blow out coil 23 to the rheostat 19. 2a is a controller handle which when moved over the various power notches on the controller engages contacts 191, 192, 193, 19a, 195, 196 and 19'7", cutting out more and more of the resistance. 25 are motors by which thevehicle is driven. The solenoid 13 is connected to the contacts 196, 197, so as tobe in shunt with the last section of the rheostat 19. 26 are lamps arranged inside the drum 1 and adapted to illuminate the advertisement which is being displayed, the lamps being connected in shunt with the power circuit 27 is amagnetic brake. The motors 25 are so connected to the controller handle 2% that at starting they are in series as shown in Figure 3 and afterwards in parallel as shown in Figure 4. 28 is a line switch.

In operation the controller handle when on the first power notch engages the contact 191 as shown in Figure 3, the whole of the resistance is in and consequently the solenoid is energized, the core.12 is drawn up wards and the pawl 1a which is connected thereto by the stirrup 10 engages with a tooth. of the ratchet wheel 15 and turns this latter and with it the drum 1 for one-sixth of a revolution so that a "fresh advertisement is displayed in the opening 2. When the controller handle is moved to the second power notch it engages the contact 193 cutting out some of the resistance, the solenoid 13 remains energized and consequently no movement of the drum at occurs. When the controller handle 24 is moved to the third power notch it engages the contact 195 outting out more of the resistance, the solenoid 13 still remains energizedand no movement of the drum 4 takes place. When the controller handle 24 is moved to the fourth power notch it engages the contact 197 and the whole of the resistance 19 is cut out, consequently the solenoid 13 ceases to he energized and the core 12 is moved back to its original position as shown in Figures 1 and 2 and the pawl 14 is ready to engage another tooth of the ratchet wheel When the controller handle is moved to the fifth power notch it engages the contact 194:, some of the resistance is now in and the solenoid 13 is again energized and the drum a is moved by the pawl 1 1 so that the advertisement is changed for the second time. When the controller handle 24 is moved to the sixth and seventh power notches, it engages the contacts 195 and 196 respectively cutting out more resistance, the solenoid 13 remaining energized so that no movement of the core 12 takes place. When the controller handle is moved to the eighth power notch the whole of the resistance is cut. out, the solenoid 13 ceases to be energized, and the core 12 is moved back to its original position, the pawl 1 1 being then ready to engage another tooth of the ratchet wheel 15. l/Vhen the controller handle is moved tothe first brake notch as shown in Figure 5 it. engages the Contact 191 so that the .whole of the resistance is in and the solenoid is again energized and the drum 4: moved by the pawl 141- and the advertisement is changed for the third time. the controller handle is moved to the second, thirchiourth, fifth, and sixth hralre notches it engages in succession the contacts-192, 193, 19st, 195, and 196, the resistance being, gradually cut out, the solenoid remains energized and conse quently there is no movement of the corelil and drum 4. l/Vhen the controller handle is moved to the seventh power notch, it engages the contact 197, and the whole of the resistance is cut out; the solenoid 12 ceases to be energized and the core 12 is moved back to its original position and the pawl 11 is ready to engage another tooth oi the ratchet wheel 15. 7

Thus, in a normal. operation of. switching on power to full speed and subsequently bringing the car to rest again by means of the electric brake, three actuations 0t theadvertising device will be effected.

Preferably the solenoid 13 is so set and adjusted that its core 12 is actuated when a current of a certain predetermined strength flows in the circuit of the vehicle motor; the core 12 will then drop whenever the strength of the current falls below this value, and the. core 121will be raised andthe advertisement changed whenever the strength of the currentexceeds this value.

It is to be understood that the showing in Figures 3, 1 and 5 is merely illustrative and that the invention is not limited to any, particular type of electric controlling mechanism or electric brake. a I
